OLYMPIA, Wash. (AP) — The father-in-law of a missing Utah woman is in court on Monday seeking to suppress evidence used to charge him with voyeurism and possession of child pornography.

Steven Powell has argued that a search warrant used to collect files from his home last summer was a fishing expedition to seek evidence that might link his son, Josh, to Susan Powell's 2009 disappearance.

Authorities say they found thousands of images of females being videotaped without their knowledge, including Susan Powell. Some of the girls were as young as 8 years old.

Steven Powell has pleaded not guilty. His trial is scheduled to begin in two weeks.
